Fiber

During an ad lib diet, an additional 14 g/day fiber
for >2 days is associated with a 10% decrease in energy intake
and body weight loss of 1.9 kg over 3.8 months. Obese individuals
may exhibit a greater suppression of energy intake and body weight
loss by a higher fiber intake in both overweight/obese and lean
subjects.

Vinegar

Supplementation of a high carbohydrate
food (ie: bread) with vinegar reduced postprandial responses
of blood glucose and insulin, and increased the subjective rating
of satiety. Researchers also point out the potential benefits
of fermented and pickled foods since they also contain acetic
acid.

Meal Size and Dietary Fat (Obese Subjects)

A high fat meal may lead to over-consumption of calories, particularly
when hunger is high (light lunch). This over-consumption is not
compensated for by reduced intake of calories later. Possible
interpretation: If you had a light meal, your next meal should
be low in fat. A full meal should precede a high fat ad lib meal.
